Had a serious crash of my Tiger 2(not 60 size), so got a fuse kit and overlayed where the new wood met the old, right about mid plane. Extra epoxy, double wood, and all this reinforcing the plane looked the same after recovering, but gained substantial weight. Goldberg suggests 4C from .40 to .50, but I have a Saito 56 and need more HP. Looking at a Saito 80 to pull the weight. Is that too much engine for the frame? It's a 40 size kit.
